HIGH-WATER ALARM.

SPECIFICATION forming part of Letters Patent No. 441,982, dated December 2, 1890.

Application filed May 19, 189i). Serial No. 352,295. (No model.)

To a/ZZ whom t may concern:

Be it known that I, IsAIAH Il. SIMPSON, of Brunswick, in the county of Cumberland and State of Maine, have invented a new and Improved High-Vfater Alarm, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which-n Figure l is a vertical transverse section ot' my improved high-water alarm. Fig. 2 is a vertical transverse section taken on a plane at right angles to that of Fig. l; and Fig. 3 is a perspective view, partly in section.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to construct a highwater alarm for water-towers and tanks vwhich may be used in freezing weather without danger of becoming inoperative, which will give instant alarm at the engine-room in case of high water, and which will automatically restore itself to its original condition after having given an alarm.

My invention consists in a spring-suliiported bucket having an apertured bottom and pro vided with a discharging-siphon, an electric circuit-closer arranged to be operated by the downward movement of the bucket, and means for discharging the water from the tower or tank into the bucket, all as will be hereinafter more fully described.

Upon a pipe A, projecting from the tank or water-tower l5, is supported the housing C, within which is arranged an elbow D, which is screwed onto the end of the pipe A. The elbow projects downwardlyT and is furnished with a nozzle E. To the top of the elbow D is secured a block F, in which are inserted tubes o c for receiving the guide-rods i) b', attached to the bucket G. The guide-rod b extends through the top of the block F, and is iiattened and provided with a pin c. To the top of the block F is attached a spring d by the screw e, the said spring extending forward underneath the pin c ot the rod b. The spring tl carries the contact-point f, below which in the block F is inserted a contact# point g. The spring d and contact-point g are connected by wires h t with a battery and a distant-alarm device, such as a bell. The

spring d supports one side of the bucket G,

the opposite side being suspended from a spiral springj, connected with the bucket and attached tothe block F. The bucket G is provided with a hopper-shaped bottom to insure the complete passage of all the water, and in one side of the bucket is inserted a siphon H, the longer arm of which projects below the bottom of the bucket, and is cut ott diagonally to provide a point 7.5, which will 6c permit the passage of the last drop of water from the siphon, thereby preventing the formation of ice at the end of the siphon in cold weather.-

Upon the pipe A, connecting the alarm device with the tower or tank B, is formed an oblique slot I, the material ot the pipe at the tank sido of the slot being rounded to facilitate the discharge of water through the slot,

while the material at the opposite side of the 7o slot is thickened, forming a shoulder Z, which impedes the water and causes a small amount to pass through the slot I. lVhen the water' rises in the tank or tower so that it enters the pipe A in a small stream, it iiows out through the slot I when it has risen suiciently in the tank or tower to give the water discharged through the pipe A avelocity which will cause it to leap across the slot I.

The discharge from the said slot I is dimin- 8o ished or stopped, and most or all of the water goes into the bucket G, and although a portion ot' the water is discharged through the holein the bottom of the bucket G it will not all escape that way, and as soon as the bucket lVhen the bucket lls to such an extent as 9o to flow out through the Siphon K, the said siphon begins to act and the bucket is quickly emptied by the combined discharge of the Siphon and the hole in the bottom of the bucket, when the circuit is broken between 9g the points fg. lf the flow of water continues, p

the bucket is again iilled and the circuit is again closed, thereby giving a second alarm, and so on. When the water descends below the pipe A, the bucket G returns to its norroo mal position, and is ready for another operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a high-Water alarm for tanks and water-towers, the combination of a discharge-- pipe placed at the high-water mark of the tank or towel', a springeupported bucket arf ranged to receive the Water discharged'by the discharge-pipe, an electric-circuit closer operated by the movement of the bucket, an electric alarm, and electrical connections, substantially as specified.

2. In a highwater alarm for tanks and water-towers, the combination, with the tank Ol tower, of vthe pipe A, placed at the highwatenark and provided with the oblique alarm mechanism arranged to be operated by 'the movement of the bucket, substantially as specified.

'4. In a high-water alarm for tanks and water-towers, the combination of a water-discharge pipe arranged at the high-water mark of the tank or tower, a spring-supported bucket arranged for receiving the water from the dischargepipe land provided. with a hopper-shaped bot-tomfurnished with-a discharge aperture, and .la siphomconnectedj ,withthe bueketnear the top thereotfandfadaptedto be charged by the filling of .-the bucket,gthe said: Siphon being provided'wvfitlizapointed dischargeeudnd alarmmechanism arranged to be operated by the movement of the bucket, Substantiallyas specified.`
